chiclet keyboard
     
         A {keyboard} with a small, flat rectangular or
        lozenge-shaped rubber or plastic keys that look like pieces of
        chewing gum.  (Chiclets is the brand name of a variety of
        chewing gum that does in fact resemble the keys of chiclet
        keyboards).  Used especially to describe the original {IBM
        PCjr} keyboard.  Vendors unanimously liked these because they
        were cheap, and a lot of early {portable} and {laptop
        computers} were launched with them.  Customers rejected the
        idea with almost equal unanimity, and chiclets are not often
        seen on anything larger than a digital watch any more.
